Detection of natural crack in wind turbine gearbox [PDF]
Renewable Energy, 2018 Abstract One of the most challenging scenarios in bearing diagnosis is the extraction of fault signatures from within other strong components which mask the vibration signal. Usually, the bearing vibration signals are dominated by those of other components such as gears and shafts.
